ABSTRACT:
A method for selectively separating Zn from an acidic aqueous solution containing ions of Zn and Fe obtained by leaching of blast furnace dust using hydrochloric acid comprises first precipitating Fe from the solution and then treating the resultent Zn-containing solution with an alkali to precipitate Zn.
The Zn-containing solution is treated in two stages; in the first precipitation step the pH is adjusted to from 4.0 to 4.3.
